EN Purpose: Modern Machines for precision products for three dimensional machining have by milling over 20.000 rpm. Differences between hard and soft machining have influences on concept of machines. Stiffness and rigidity are characteristics and variables which caused the precision and quality of machined part. Design/methodology/approach: This paper introduce some of interesting modern machine tools with different concept as DCG (Drive in Centre of Gravity - Mori Seiki), LAF (Look Ahead Function on Machine - Sodick), high speed 20.000 - 60.000 rpm, linear drive, etc. The way from idea to machined part will be shown. Findings: To achieve high precision it is necessary to fill out many request function on machine. Results on machined part depend also from machined material (hardness, structure, size of crystals). Research limitations/implications: Engineers job is to prepare the optimal CNC (PNC) program on connection of CAD - CAM software's. After all mentioned factor test work piece is machined and measured. Originality/value: Comparison between results data on plan and measurement shows us the reality and give us decision around high precision product.
